Original Tatung monitor, has dark areas on the screen and low brightness level. Brightness level is maxxed out and contrast has no effect. I have seen one website offering monitors and tubes for sale and saying they have a mod to reduce the heater voltage because high heater voltage is what damages the tube and causes the dark spots. So the question is, does this mod work as advertised and is there something else (such as bad caps) that could be causing the dark spots? Thanks.
